The Little Mix star seems keen to show off as much flesh as possible having shrunk several dress sizes since winning The X Factor back in 2011.

Performing at Stratford's Queen Elizabeth Olympic Park, Jesy rocked a T-shirt emblazoned with a 'Parental Advisory: Explicit Content' logo - which usually appears on CDs as a warning to parents that swear words, sexual material or lyrics alluding to violence might feature in the songs.

Tied at the waist to show off her stomach, Jesy teamed the top with black and white striped leggings with large cutaway panels to show off her legs - and new tattoo.

The slashed Beetlejuice trousers allowed the 22-year-old to flaunt the new inking, which reads: "A lion never loses sleep over the opinion of sheep."

Meanwhile, Perrie Edwards and Leigh-Anne Pinnock also flaunted their flat midriffs during their Friday gig.
